问题
I'm using the Google signin Javascript API (that is, the gapi-signin-button) on a webapp. The app is served by a gulp server, binding to 0.0.0.0. The login process works when I develop locally, but when I run on a remote server and access the page via the public IP, I get the following signin error:
Error: invalid_request
Permission denied to generate login hint for target domain.
I have both localhost:PORT and SERVER_IP:PORT in my Authorized JavaScript origins. Other SO answers have said I should be binding to localhost instead of other interfaces, but that doesn't apply here since if I bind to localhost the server can't be accessed remotely. What do?

I had this same problem and just figured it out. You can't use numerical ip addresses (like http://0.0.0.0) as redirect uris in Google. It has to be an actual url, like http://mycompany.com.
